Embodiment 1

[0040] Such as Figure 1-3 As shown, the MDC110 rectifier module frame cover 1 has two grooves 10 evenly distributed on the front of the frame cover, and the grooves are arranged along the width direction of the cover plate. The setting of the groove reduces the stress, thereby reducing the amount of deformation. The back of the groove is provided with reinforcing ribs 11. The back of the frame cover includes 3 protrusions 12 .

[0042] (1) Debug the rectifier module MDC110 frame cover test sample with the plastic tooling, and determine the reverse deformation stroke S 终

[0043] (1-1) Fill the hopper of the injection molding machine with the rectification module MDC110 frame cover raw materials, the rectification module MDC110 frame cover raw materials include: 95wt% PBT, 5wt% PBT recycled materials; adjust the process parameters of the injection molding machine, and...

Embodiment 2

[0061] Such as Figure 6-8 As shown, the front of the MDS75 rectifier module frame cover is arranged in two rows, with three pole piece installation holes 50 arranged in one row, and two pole piece installation holes arranged in one row. Vertical grooves 51 are processed between the pole piece mounting holes, and transverse grooves 52 are processed between two rows of pole piece mounting holes. The setting of the groove reduces the stress, thereby reducing the amount of deformation. The back of the slot is provided with five protrusions 53 corresponding to the mounting holes of the pole pieces. The non-protruding part is the shaping area 54 .

Abstract

The invention belongs to the technical field of finishing module preparation. A preparation method of a rectifier module frame cover comprises the following steps of (1) debugging different rectifiermodule frame cover test samples by using a shaping tool, and determining a reverse deformation stroke S final; and (2) when a related frame cover is injected by an injection molding machine through ashaping tool, firstly removing burrs of a glue opening, then placing a shell frame cover on a shaping device, enabling the back face of the frame cover to face upwards, applying pressure to the framecover through a hand press, and realizing reverse deformation and the reverse deformation stroke S final, and therefore, completely counteracting the deformation amount of cooling shrinkage of the frame cover. The problem of cooling distortion of the rectifier module frame cover is solved.

Description

technical field [0001] The invention belongs to the technical field of rectification modules, and in particular relates to a method for preparing a frame cover of a rectification module. Background technique [0002] At present, the raw material of the rectifier module shell is PBT, which is prepared by injection molding process. After production, a part of the shell will be deformed and twisted during the cooling process due to structural problems. Therefore, it is necessary to improve the existing preparation method, so that the shell frame cover is flat and there is no gap when mating with the corresponding supporting parts. Contents of the invention [0003] The purpose of the present invention is to provide a method for preparing the frame cover of the rectifying module to solve the technical problem of deformation and distortion caused by the existing preparation method of the frame cover of the rectifying module. [0004] In order to solve the above technical prob...
